README for IPC-Run3 0.043 IPC::Run3 - run a subprocess in batch mode (a la system) on Unix, Win32, etc. SYNOPSIS use IPC::Run3; # Exports run3() by default run3 \@cmd, \$in, \$out, \$err; run3 \@cmd, \@in, \&out, \$err; This module allows you to run a subprocess and redirect stdin, stdout, and/or stderr to files and perl data structures. It aims to satisfy 99% of the need for using system, qx, and open3 with a simple, extremely Perlish API and none of the bloat and rarely used features of IPC::Run.
